Abstract
The utility model provides an installation mechanism of low pressure casting organizational security temperature stove thermocouple, including protection tube and ring flange, protection tube one end is connected with flange seal, the thermocouple attachment hole has been seted up on the ring flange, be equipped with the thermocouple fixed orifices in the protection tube, the mounting hole communicates with each other with the fixed orifices, during the use, the thermocouple is fixed in the thermocouple attachment downtheholely to stretch into in the thermocouple fixed orifices. The utility model discloses simple structure, the installation is very convenient with the dismantlement, and thermocouple protective pipe and flange seal connect, guarantee its leakproofness, the unable thermocouple protective intraduct that gets into of messenger's steam, the thermocouple element just is difficult to the corruption, and life increases greatly, reduces the damage frequency of thermocouple. Because of seamless between pillar and the ring flange, so steam again can't spill over, the inside aluminium temperature degree of heat preservation stove has been guaranteed from the gap.
Description
Technical field
The utility model belongs to casting technology field, particularly a kind of installing mechanism of low pressure casting machine holding furnace thermocouple.
Background technology
Low pressure casting machine holding furnace usually will arrange thermocouple and carry out temperature detection; thermocouple is arranged on body of heater by ring flange; rock in body of heater to protect thermocouple; need to install protection tube additional position thermocouple and protect; after protecting tube is installed; and do not fix between ring flange, during the work of holding furnace inner inflatable, high temperature hot gas can be overflowed from the gap between pillar and ring flange.And high temperature hot gas directly contacts with thermocouple, thermocouple can be caused to corrode and accelerate, in production process, frequent shutdown changes thermocouple, and the unit efficiency of product is reduced greatly.
Utility model content
The deficiencies in the prior art in view of the above, the purpose of this utility model is the installing mechanism providing a kind of low pressure casting machine holding furnace thermocouple, prevents thermocouple from being damaged by hot gas.
For achieving the above object and other relevant objects, technical solutions of the utility model are as follows:
A kind of installing mechanism of low pressure casting machine holding furnace thermocouple; comprise protection tube and ring flange; described protection tube one end is connected with flangeseal; described ring flange offers thermocouple mounting hole; be provided with thermocouple fixing hole in described protection tube, described installing hole communicates with fixing hole, during use; described thermocouple is fixed in thermocouple mounting hole, and stretches in thermocouple fixing hole.
As preferably: described protection tube one end is provided with the externally threaded joint of band, and described ring flange offers the threaded connection hole coordinated with joint, described protection tube is connected with threaded connection hole by joint with ring flange.
As preferably: described ring flange central authorities have a boss, and described boss offers tapped shoulder hole vertically, and the hole that wherein internal diameter is less is thermocouple mounting hole, and the hole that internal diameter is larger is threaded connection hole.
As preferably: the screw thread of described threaded connection hole is 55 ° of internal threads made in Great Britain.
As preferably: described joint screw thread is the external screw thread made in Great Britain of 55 °.
As preferably: described boss and protection tube lay respectively at the both sides of ring flange.
As mentioned above; the beneficial effects of the utility model are: structure is simple; mount and dismount very convenient; protecting tube is connected with flangeseal; ensure its sealing, make hot gas cannot enter protecting tube inside, thermocouple element is just not easy corrosion; service life increases greatly, reduces the damage frequency of thermocouple.Because of seamless between pillar and ring flange, therefore hot gas again cannot overflow from gap, ensure that the aluminium coolant-temperature gage of holding furnace inside.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present utility model and effect easily.
As shown in Figure 1; a kind of installing mechanism of low pressure casting machine holding furnace thermocouple; comprise protection tube 2 and ring flange 1; described protection tube 2 one end and ring flange 1 are tightly connected; ring flange 1 offers thermocouple mounting hole 13; thermocouple fixing hole 22 is provided with in protection tube 2; described installing hole communicates with fixing hole; during use; thermocouple is fixed in thermocouple mounting hole 13; and stretching in thermocouple fixing hole 22, ring flange 1 is connected with body of heater with bolt by flange hole 14, and thermocouple and protection tube 2 stretch in body of heater.
Further scheme is, described protection tube 2 one end is provided with the externally threaded joint 21 of band, and ring flange 1 offers the threaded connection hole 12 coordinated with joint 21, described protection tube 2 is connected with threaded connection hole 12 by joint 21 with ring flange 1.
In this example, ring flange 1 central authorities have a boss 11, boss 11 offers tapped shoulder hole vertically, shoulder hole runs through ring flange 1 center, shoulder hole bigger diameter end is near ring flange 1, miner diameter end is away from ring flange 1, the hole that wherein internal diameter is less is thermocouple mounting hole 13, and the hole that internal diameter is larger is threaded connection hole 12.Described boss 11 and protection tube 2 lay respectively at the both sides of ring flange 1.
In order to ensure the sealing property of ring flange 1 and protection tube 2, the screw thread of threaded connection hole 12 described in this example is 55 ° of internal thread G3/4 made in Great Britain ", the screw thread of described joint 21 is the external screw thread G3/4 made in Great Britain of 55 ° that want with threaded connection hole 12 to adapt to "; These 55 ° of inch screw threads more easily seal than 60 ° of metric thread.
After adopting said structure, it is inner that hot gas cannot enter protecting tube 2, and thermocouple element is just not easy corrosion, and service life increases greatly.Because of seamless between pillar and ring flange 1, therefore hot gas again cannot overflow from gap, ensure that the aluminium coolant-temperature gage of holding furnace inside.Thermocouple is changed number of times and is reduced by 97%, improves the unit efficiency of product, reduces production cost.Before improvement, monthly chargeable heat galvanic couple 30.After improvement, monthly chargeable heat galvanic couple 1.Greatly reduce thermocouple break frequency.
Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
